Scientists discover nursery ground for sand tiger sharks in Long Island's Great South Bay

Scientists and veterinarians working for WCS's New York Aquarium have discovered something noteworthy in the near shore waters of Long Island's Great South Bay: a nursery ground for the sand tiger shark, a fearsome-looking but non-aggressive fish.

The discovery was made by researchers who have collected a wealth of information on sharks in local waters over the past four years through the use of acoustic tags, devices that enable scientists to remotely track marine animals as they swim through their environment. These data have helped the scientists confirm the existence of the nursery in Great South Bay, one of the rich estuaries found along Long Island's southern shore. Only a handful of sand tiger shark nursery grounds have been identified, one of which is in the waters of Massachusetts.

Shark Social Networking: Shark Migrations Studied With Underwater Robot Along Delmarva Peninsula


ScienceDaily (Oct. 17, 2012) — University of Delaware researchers are using an underwater robot to find and follow sand tiger sharks that they previously tagged with transmitters. The innovative project is part of a multi-year partnership with Delaware State University to better understand the behavior and migration patterns of the sharks in real time.
"In the past week our new, specially equipped glider OTIS -- which stands for Oceanographic Telemetry Identification Sensor -- detected multiple sand tiger sharks off the coast of Maryland that were tagged over the past several years," said Matthew Oliver, assistant professor of oceanography in UD's College of Earth, Ocean, and Environment. "This is the first time that a glider has found tagged sharks and reported their location in real time."
OTIS is a remote-controlled device that looks like a yellow torpedo and normally darts through the ocean to sample water conditions. Oliver outfitted the apparatus with acoustic receivers that can recognize signals given off by the sharks' transmitters as they travel through coastal waters, rapidly reporting the encounters.
